The Optibelt 25 AT5K6 / 6000 AFX is a timing belt from the Alpha Flex series. It uses an AT5 profile with a 5 mm pitch and a 6000 mm length. Before you install it, inspect the drive and sheaves.
A new belt will not correct worn or misaligned components. Check sheave grooves for wear, nicks or debris, and confirm that flanges are secure. Verify that shafts turn freely and that bearings do not have play. Misalignment or a damaged sheave can shorten the life of any timing belt, including this one.
Confirm the marking on the old belt matches the AT5 profile, 5 mm pitch and 6000 mm length. The Optibelt 25 AT5K6 / 6000 AFX is a timing belt built to those dimensions. If the drive uses more than one belt, replace the set together so loads stay even.
